s claims. (cl. 24a-7) (Granted under the act of March 3. 1883, as amended Apr-i130, 1928; 370 0. G. 757) A further object of this machine is t provide an apparatus that will provide means whereby a circular core will be evenly and quickly covered.

A further object of this invention is to provide a simple and efficient apparatus for covering circular cores economically and yet produce a better and more even article.

With the above and other objects and advantages in view, the invention consists of features of construction, arrangement and operation of parts which will appear in the specification and be finally pointed out in the claims.

While a preferred embodiment of the invention is shown, it will be understood that slight changes in form and minor details of construction may be resorted to without departing from the spirit of the invention and fall beyond the scope of the claims.

Referring now to the drawing, in which similar characters and references in the several figures indicate identical parts:

Fig. 1 is a perspective view of the apparatus embodying the invention.

Fig. 2 is a sectional view taken on the lines 2 2 of Fig. 1.

Fig. 3 is a detail View illustrating a relative arrangement of the strand and core as produced by the operation of the improved apparatus.

Reference now being had to the drawing by numerals, in which I0 indicates a base board, upon which is secured a base I I which is adapted to receive a sliding carriage I2 within the recess I3, carriage I2 has upturned ends I4 to which are secured clamp-holding members I5 adapted to receive and hold clamps IB thereon. Secured to the sliding carriage I2 at a position intermediate the ends thereof is a feed arm II having secured thereto at its forward end a split nut I8 having threads therein which mesh with the threads on a feed screw I9 which is suitably supported at each end by supports 20. The feed screw I9 has a pulley 2I secured to one end thereof, and

' the feed screw is adapted to be rotated 'by means of a belt 22 connecting pulleys 2| and 23. Pulley 65 23 is mounted at one end of a hollow shaft 25 and a pulley 24 mounted on the other end of this shaft is adapted to be driven by an electric motor and belt not shown. Suitable supports 26 are placed on the baseboard I0' to support the 'hollow'shaft Secured to the base I I by well-known means isH a bracket 2'I to which is rigidly secured a sleeve 28. The sleeve 28 has a slot 29 therein which is adapted to receive the core which is to be wound, the sleeve 28 has a hinged portion 29a which can be lockedin fixed position by a spring catch 30. In the forward end of the sleeve 28 is a split guide 3l, half of which is fixed to the rigid portion of sleeve 28 and half being xed to the hinged portion 29a.

The end of the machine at which the winding takes place consists of a bobbin carrying wheel 33 having a slot 34 therein which corresponds and aligns itself with the slot 29 inthe sleeve 23. The slot is adapted to be closed by a pivoted gate 35, thereby completing the periphery of the carrying wheel 33. The bobbin carrying wheel 33 has a stem thereon adapted to support the bobbin 3B which is rotatably locked to the stem by a slotted and recessed locking plate 31, also attached to the bobbin carrying wheel 33 by well-known means is a tension plate 38 which is 'adapted to place a tension on the thread 'I' while the core R is being wound.

Co-acting with the periphery of the bobbin carrying wheel 33 is a rubber-tired wheel 33, which is rigidly secured to the end of the feed screw I9. f

The bobbin carrying wheel 33 is thereby caused to rotate by the rubber-tired wheel 39 when the feed screw I9 is rotated by the electric motor, not shown.

In winding cores of any type, lt is usual to begin at the left and wind toward the right, and in this instance the core being wound is passed through the slots 34 down into the bobbin carrying wheel 33 and slot 29 in the sleeve 28, the split guide 3| is closed and the gate 35 is moved into position over the slot 34 in the bobbin carrying Wheel 33. The core, having been stretched tight, will then be secured in place by clamps I6. The clamps- I6 hold the core against rotation at all times so that there is no twisting effect on the;

core during the winding thereof. When the winding has progressed to the point where right-hand stop I5 will strike the base II the operator can loosen the clamps IB, grasp the core already wound and while holding it in a taut position,

return the sliding carriage l2 toits extreme riht position and refasten the clamps II to the core, then the split nut il can be closed on the feed screw Il and the core at this time will then be in a position so that the winding action can be repeated.

The winding thread from the bobbin Il is drawn through tension plate 38 and is then carried around the core over toward the operator. A loop is formed and passed back through slot 3l in the bobbin carrying wheel and is pulled down within the opening in the split guide Il. The loop is held in the left hand and the right or free end of the thread is held in the right hand. The bobbin carrying wheel Il is started to rotate clockwise by means of the motor, not shown, and thus the thread is wound onto the core, the proper spacing of the thread being accomplished by the feed screw. When the winding is complete, the loop at the leftis withdrawn from the slot 34 in the bobbin carrying wheel Il. The clamps I6 are released, the thread is cut near the tension plate Il and this end is passed through the loop, previously referred to. The free end of the thread at the right ofthe core is used to draw the loop beneath the thread, which has already been wound on the core, thus forming a lock on both free ends of the thread which are then cut close.` To wind the particular arrangement shown in Fig. 3, a hook is attached to the right hand clamp and is inserted in the fold to tighten the core for winding. The tension plate 38 will at all times control the tension of the winding and with the aid of the feed screw I9 will accomplish a neat, tight and even winding. In actual operation it has been proventhat this apparatus applies winding to a core at the rate of 24 inches per minute.

The invention exemplifies a winding machine by which tow ropes for aerial targets can be wound in such a manner that they will outlast any previous tow rope that has been used for this purpose.

The invention is not to be understood as re- 2. An apparatus for winding a strand on a core comprising a U-shaped sliding carriage means positioned on the upturned ends of said U-shaped sliding carriage for holding said core against rotation, means for distributing said strand evenly and progressively upon said core, means for holding said strand while said core is being wound, and means for tensioning said strand during thewinding operation.

3. An apparatus for winding a strand on a core comprising a U-shaped sliding carriage, means positioned on the upturned ends of said U-shaped sliding carriage for holding said core against rotation, means for distributing a strand evenly and progressively upon said core, and winding means adapted to hold said strand while said core is being wound, said winding means also being adapted to hold means for tensioning said strand during the winding operation.

4. An apparatus for winding a strand on a core comprising a U-shaped sliding carriage, means positioned on the upturned ends of said U-shaped sliding carriage for holding said core against rotation, means for distributing a strand evenly and progressively upon said core, said holding means adapted to travel in commotion with said stricted to the details set forth, since these may be modified within the scope of the appended claims without departing from the spirit and scope of the invention.

Having thus described the invention, what is claimed as new and desired to secure by Letters Patent, is: v
